Add three SomaFM stations:
And update the links for DEF CON Radio.
I also (perhaps boldly) updated the
.dtd since it didn't appear to match the actual tokens/formatting of the file. If I'm offbase, happy to remove those changes or update them/the config file!
I also snuck in a URL update to the mailing list, but also happy to move that into a separate PR if that's better.
Thanks again for this software!
